Referring to the drawings, there is illustrated a nutv device inconnection with securing trimming strips to windows and the like. Thedevice illustrated is particularly, though not exclusively, useful inautomobile body construction for easily and quickly securing trimmingstrips of wood or metal to the body.

The installation shown in the drawings lncludes a metal window framepart or sill support 1 having lts exposed surfaces cov- .1 ered withupholstery 2, a glass 3 which may or may not be raised and lowered, aplui rality of metal trim or sill strips 4 formingV a casing for thevglass, shiftable nut devices secured to the frame part and screws 5 forengagement with the nut devices to secure the strips in place.

The frame part 1 is initially prepared for the nut device by forming adepressed portion 6- therein about midway between the glass 3 and theinner edge of the frame. At the bottom of the depressed portion 6 isformed an aperture 7 having opposed notches 8 to receive the nut deviceas hereinafter described. v

The nut device includes a nut holder 9 pressed from a single piece ofmetal and a nut 10 also pressed from a single piece of metal. The nutholder is provided with a base portion 11 having an aperture extendingvtherethrough, opposed relatively long resilient fingers 12 extendinglirstbelcw the base portion 11- and then sloping toward each other at`the opposite side of. the baseportion. Opposed shorter projections 13are Valso formed from the base of the holder and extend in the samegeneral direction as the fingers 12, as best illustrated in Fig. 6. Thenut 10 has a base lffrom which is pressed a boss 15 screw-threaded onthe inside for reception' of a screw 5. Parallel diverging flanges 16extend from the base 15 and are presented at two sides of the nut. Theseflanges 16 terminate in substantially the same plane as the end ofthehoss 15 as illustrated in Fig. 11, and provide guides for the nut.

The nut unit is assembled at the point of manufacture and while the nutis shiftahle relative to the holder it is held in assembled relationtherewith hy the fingers l2 which overlie the nut suiiiciently toprevent its. hecoming disengaged therefrom. The aperture in the base 11of the nut holder is larger than the boss, lout the boss is preventedroum entering the aperture and interering with the operation of the nutby the flanges 16 which span the aperture and guide the nut along thebase portion 11 of the Aholder asillustrated in Fig. 6.

The trim strip 4 is formed from a singie piece of metal and is providedwith a plurality of screw receiving apertures 17 surrounded by taperedwalls 18to provide for countersinking the heads of the screws 5.

Assembly of the installation may be effected by irst securing the nutyunit to the frame part 1. This may be accomplished by entering one ofthe lingers 12, which may or may not be contractible and expansible,into one of the' notches 8 at one side of the aperture i so that aAhook-shaped portion 19 formed at the end of the finger may hook over theouter face of the'frame part 1 in the depressed portion 6 as illustratedin Fig.l7. Then the other linger maybe snapped through the.V aperture sothat its hook-shaped portion 19 may also overlie a portion of the framepart thereby to lar in outline, is held against rotation by the fingers12 and the projections 13. The nut is free to shift transversely in alldirections re1- ative to the nut holder and the frame 1 and is limitedin its movement by cooperation between the flanges 16 of the nut and thefin ers y12 and also by cooperation between Ithe oss 15 and theprojections V13.- After the upholstery 2 has been stretched over theframe 1 the trim strip 4 may be placed over the upholstery and a screw 5entered \in the aperture 17. This screw 5 passes through the upholstery,through the yaperture 7 in' the depression 6 and enters the threadedboss 15 ofthe nut. By turning the screw 5 it may be threaded into theboss 15 as best illustrated in Fig. 2. During the screwing togetheroperation, the nut may shift in any transverse direction, as abovedescribed, so as to -alignp'itself with the screw. v 1 v Where the trimstrip is usedl at the edge of a frame, as in the Window frameillustrated in the drawings, it is sometimes necessary to shift the strisidewise so that it may be aligned with t e edge of theframe or pressedagainst the glass as illustrated. in Fig. 3. This movementrmay begreater than the usual shifting movement of the nut for correctingmisaligned holes as shown and described inv cooperatin applications andtherefore pro-.

vision has een made for permitting greater sidewise shifting'movementofthe nut to provide for movement of the strip.. The drawings illustratethe fact that the nut may shift to a greater extent toward the projecti,ons 13 than toward the fingers 12. Thus the Ii'otches 7 at thesides of the apertures are `formed lengthwise of the strip so that whenthe nut unit is secured to the frame 1 the projections 13 are locatedcrosswise of the strip to permit greater shift of the strip in theproper direction as fully illustrated by Figs. 2 and 3.

During `the assembling operation of the in` stallation the screws areturned to tighten the nuts but before iinally fclaniping the strip inplace it is shifted to its proper relation with the frame and then thescrews are given a final twist to clamp the strip tightly against theframe 1 with the upholstery gripped Y tightly beween them.

While there is shown and described a pre-` ferred embodiment of theinvention, it will be understood that. changes involving omission,alteration, -substitution and reversal of parts and even changes in themode of operation may be made without departing from the scope of theinvention, which is best defined in the appended claims. s

combination, a pressed metal nut holder and a pressed metal nut, saidholder having a base portion presenting` an aperture therethrough `to'permit a screw to pass therethrough, op-

posed fingers extending therefrom and overlying portions of the nut tohold the nutI in assembly withthe holder, a boss presented by said nutand extending toward the base of the holder, opposed flanges presentedby said nut having their edges terminating in subs tantially'thesame`plane as the end of said boss to prevent entrance of said boss inthe aperture provided in the base of the holder and opposedprojections'extending from the base of saidv holder to limit-'themovement of said nut in any direction generally crosswise relative tosaid fingers.
